4. Which statements are useful for explaining the ratio of black-coated to brown-coated mice in the F2 generation?
Select all that apply.
a. The F, male produced two kinds of sperm, half carrying
an allele for black coat color, and half carrying an allele for
brown coat color.
b. The F, female produced two kinds of eggs, half carrying
an allele for black coat color, and half carrying an allele for
brown coat color.
c. An approximately three-to-one ratio of black to brown
coated mice in the F2 generation is accounted for by the
black allele being dominant over the brown allele.
d. The brown allele segregates together with the black
allele and disappears in the F, generation.
